Service Integration and Management (SIAM) is an approach to managing multiple suppliers of services (business services as well as information technology services) and integrating them to provide a single business-facing IT organisation. It aims at seamlessly integrating interdependent services from various internal and external service providers into end-to-end services in order to meet business requirements.〔Goldberg M., G. Satzger and A. Kieninger (2015), (A Capability Framework for it Service Integration and Management in Multi-sourcing ), forthcoming, Twenty-Third European Conference on Information Systems (ECIS), Münster, Germany.〕〔Goldberg M., A. Kieninger and H. Fromm (2014), (Organizational Models for the Multi-Sourcing Service Integration and Management Function ), Proceedings of the 16th Conference on Business Informatics (CBI).〕 == Background == Bolstering information technology capabilities and capacity using multiple external suppliers is becoming a dominant operating model for many large enterprise IT organisations. This model is commonly known as multisourcing. Sourcing from multiple IT suppliers allows an organization to maintain in-house technical teams or large single source suppliers, and become more adaptable by taking advantage of competitive marketplace behaviors which incentivise cost reduction and leverage innovation. The use of multiple best of breed suppliers can incur large management overhead costs and lead to difficulty in managing end to end (e2e)services. SIAM thinking has developed to aid that management challenge. The term SIAM was predated by the term Service Integration which has been in use since at least 2009.〔"Service Integration Deliver's Multisourcing's Promise" Euan Davis, Forrester, 2009〕 It should not be confused with the term System integration. Unlike ITIL (for IT service management) and PRINCE2 (for project management) it is not a framework and does not yet have an established body of knowledge. Instead it is largely implemented in line with proprietary models developed by large IT service providers, including Accenture, Cap Gemini, CSC, Atos, TCS and IBM to meet requirements developed by third party advisors, notably KPMG, Gartner and ISG. In UK government it is seen as a way for large governmental IT organisations to better manage and control multi-sourced operations, by compiling (and then sharing between themselves) their best practices and their most successful management methods. SIAM is a rapidly developing area of service management, and one that is closely associated with multiple disciplines including IT service management, enterprise architecture, organisational change management, quality management and risk management. Other developments in IT management, such as DevOps may well influence how SIAM evolves. SIAM is expected to mature as the framework for service management. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Service integration and management」の詳細全文を読む スポンサード リンク
